Answer:
The accurate statements are
2. The train is not an inertial frame of reference.
5. The train could be moving at a constant velocity in a circular path.
8. The train must be undergoing acceleration.
Explanation:
As we observe that the string forms an angle with the horizontal
we can formulate the force equation relevant to the given ball
similarly in the Y direction
Thus we conclude
Reminder: The illustration mentioned in the inquiry is included here as a file.
Response:
The intensity of the magnetic field is
Clarification:
The magnetic field can be calculated using the following equation:
...............(1)
Where I refers to the current flowing through the wires
To find the distance R from point 1 to m, apply the Pythagorean theorem
Inserting R into equation (1)
Answer:
A) denotes the resultant velocity of cart B post-collision.
B)
C)
D)
E)
F) Yes, kinetic energy remains conserved in this situation because both colliding bodies have identical mass.
G) Yes, momentum is conserved in every elastic collision.
Explanation:
Given:
A)
The question mentions the cars experience an elastic collision:
By applying momentum conservation principles:
denotes the resulting velocity of cart B after collision.
B)
Initial kinetic energy of cart A:
C)
Initial kinetic energy of cart A:
D)
The final kinetic energy of cart A:
E)
The final kinetic energy of cart B:
F)
Yes, kinetic energy is conserved in this case due to both masses being identical in the collision.
G)
Indeed, momentum is consistently conserved in elastic collisions.
